RECIPROCITY THEOREM
This theorem states that in any linear bi-lateral network , the current I through any branch of the network due to a single voltage source E elsewhere in the network is equal to the current through the branch of the network where the source was originally placed if the source is placed in the branch in which the current I was originally determined.
APPLICATION OF RECIPROCITY THEOREM:
In fig.(a) the source is shown and the current through resistor r_{4} is I_{1}. In fig.(b) , the source is placed in series with r_{4} and the current through r_{1} is I_{2}. By reciprocity theorem I_{1} = I_{2}.
The main limitation of this theorem is that it is applicable only to single source networks and not to multi-source networks. Another point to note is that the network should not have any time-varying element.
